Fert dosing suggestion ?

So one of my tanks is semi-high tech, the other med/low tech or I really should say low/w med light.
The low tech tank recently went through a time of BGA but is fine now. But it took double treating to rid it.
So this has made me hyper-suspicious, another way of saying paranoid of Phosphates in my water. And MgSO4.
As the result of this, when making up my Macro fert list I omitted Gh booster/MgSO4 and I am going to substitute K2SO4.
This is a ten G tank/w 2x T5 bulbs and Excel as per directions. I asked on here for someone to suggest amounts for reduced/once a week doses of the Macros. This was the suggestion: 1/4 teaspoon of KNO3 and 1/64th teaspoon of KH2PO4. But I don't know how much of the K2SO4 to dose.
I am now(till it runs out) using Flourish Comprehensive for the Micros.
So can someone give me a reduced amount dose for K2SO4 that would be in proper proportions to these other two ?
KNO3 x 1/4 teaspoon per week
KH2PO4 x 1/64th teaspoon per week
K2SO4 x ?
U.S.P.S. has the K2SO4 65 miles from my house now so I will need this dose before too long so that I can feel that I
have covered all the basses as much as I can.

BTW: One of those calculators says 843mg once a week...but how many/much teaspoons is that ?

The shortest distance between any two points is a straight line...in the opposite direction...
